Question

Quizplus · Accepted Answer

Cleavage is determined by the number and angles between well-formed planes of weakness in a stressed mineral structure. This means that a mineral with many well-formed planes of weakness will have better cleavage than a mineral with fewer planes or poorly formed planes. The angles between the planes also play a role in determining the quality of the cleavage, with certain angles resulting in a smooth and even cleavage while others can result in a rough and uneven one. Hardness and thickness can affect how easily a mineral will cleave, but they are not the primary determinants of cleavage. Similarly, twinning and separation of mineral grains can contribute to cleavage but are not the main factors. Iridescence and shape are not related to cleavage at all.
